MACHINE FOR MIXING LiQUlDS IN DEFINiTE PROPORTIOiNS.

SPECIFICATION forming part of Letters Patent No. 688,980, datedDeceinber 17, 1901.

I Application filed April 10, 1900. Serial No. 12,840. (No model.)

To all whom it may concern:

Be it known that I, EDWARD ZAHM, of Syracuse, in the county of Onondaga,in the State of New York, have invented new and useful Improvements inMachines for Mixing Liq uids in Definite Proportions, of which thefollowing, taken in connection with theaccompanying drawings, is a full,clear, and exact description.

My invention relates to a machine for adding a limited amount of oneliquid in definite proportions to a second liquid, so that the two shallbe thoroughly mixed.

My invention may be applied to differentuses, such as adding anantiseptic solution to another liquid; but I have here shown it in aform particularly adapted for coloring beer, in which it is importantthat the different brews should always be of the same color and that thecolor should be uniformly distributed throughout. Extract of roastedmalt is used and has heretofore been added to the beer in the vat, cask,or barrel, natural diffusion being depended upon to distribute itthroughout the beer, not successfully, for the beer drawn from differentparts of the cask shows variation in color. In my invention thecoloring-matter is added gradually to the beer flowing through a pipe atany stage of its manufacture, so that, the rate of its flow being known,the coloring solution is uniformly added and thoroughly incorporatedtherewith.

The machine therefor consists, essentially, of a main pipe for thepassage of the beer or other liquid in considerable quantities and areservoir connected thereto by a small tube for feeding uniformly thecoloring, antiseptic, or other solution to the main liquid. Thissolution may be delivered into the main liquid by gravity or otherdesirable force.

My invention will be understood by reference to the accompanyingdrawings, in which the same reference -numerals indicate the same partsin the figures.

Figure I is a side elevation of my machine, portions being broken awayand shown in section. Fig. II is an end elevation thereof, taken atright angles to the preceding. Fig. III is a top plan View. Fig. IV isan enlarged elevation of communications between reservoir and mainflow-pipe. section of Fig. IV.

In the figures, 1 indicates the base, of any suitable construction,provided with wheels 2 2, to which is secured by straps 3 3 or otherWise the main pipe 4 for the beer, having inlet branches 5 5, withinlets 6 at their ends forattachinent of hose, or which maybe closed bycaps 7 7. The outlet end of the pipe is preferably bent up the better tomix the liquids and has outlet branches 1O 10, having outlets 11, towhich hose or pipe may be attached, or may be closed by caps 12 12. Onthe base is supported by frame 14 14 the res ervoir 15, containing thecoloring solution,

Fig. V is a vertical which flows through the outlet-tube 17, pro-- videdwith a suitable regulatingvalve, as pinvalve 16, and is delivered intothe main pipe through lower tube 30 and tip 18, preferably curved in thedirection of the flow of the beer to insure the free flow of thesolution. Between this outlet-tube and the delivery-tip is arranged asmall chamber 19, having a glass front 20, which forms a sight-feed, sothat the flow of the coloring solution through straight tip 21 may beseen. A gage might be used accurately to measure the flow of thesolution; but in most cases this may be judged with sufficient accuracyby observation. Pipe 22, provided with valve 23, leads from this chamberto the reservoir above the solution to equalize the pressure and forceback beer which might rise in the curved tip and the chamber.

24 is an opening for the introduction of the solution, and 25 theairpressure cock to equalize the pressure in the reservoir with thatofthe flowing beer 26, and 27 27 are testcocks to test the beer astocolor respectively before and after solution has been added.

The pressure on the solution in the reservoir and in the chamber must beat least as great as that on the beer that the solution may dropstraight through the chamber to the lower tube and tip and that the beermay not back up therein.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. In combination in a machine for adding uniformly to a larger quantityof one liquid,

ICO

a smaller quantity of a second, a main pipe for the flow of the firstliquid formed with inlets and outlets, a reservoir supported adjacentthereto and a small tube connecting said 5 reservoir with said main[low-pipe and means for feeding the liquids continuously into the mainpipe.

2. In combination in a machine for adding uniformly to a larger quantityof one liquid,

a smaller quantity of a second, a suitable base, a mainpipe supportedthereon with ining the reservoir with the main pipe.

3. In combination in a machine for coloring beer, a main pipe for theflow of the beer with one or more inlets and outlets, supplytubes andoutlet-tubes adapted to be connected thereto, a reservoir for thecoloring solution supported on the base above said main pipe, a smalltube connecting the botuom of said reservoir with the main pipe, saidtube being formed with an enlarged portion or chamber having atransparent face, between said reservoir and main tube, for observingthe flow of the solution.

4. In combination in a machine for coloring beer, a suitable base, amain pipe for the flow of the beer formed with one or more inlets andoutlets, a reservoir for the coloring solution sustained above said mainpipe,a small chamber having a transparent face arranged between thereservoir and the main pipe, a tube connecting-the reservoir to saidchamber and terminating in said chamber in a tip visible through saidtransparent face and a tube connecting the bottom of said chamber withthe main pipe.

5. In combination in a machine for coloring beer, a suitable base, amain pipe for the flow of the beer formed with one or more inlets andoutlets, a reservoir for the coloring solution sustained above said mainpipe, a small chamber having a transparent face arranged between thereservoir and the main pipe, a tube connecting the reservoir to saidchamber and terminating in said chamber in a tip visible through saidtransparent face, a tube connecting the bottoinof said chamber with themain pipe, and an air-pressure pipe connecting said chamber with theupper portion of the reservoir.

6. In combination ina machine for adding colorin g-matter tobeer,asuitablebase,amain pipe supported thereon for the flow of the beerformed with inlets and outlets, its outlet end beingelevated, areservoir for the coloring solution supported onthe base,:above the mainpipe, a chamber arranged betweensaid reservoir and main pipe having atransparent face, a tube provided with a valve connecting the bottom ofthe reservoirwith the top of said chamber and terminating Within thechamber in a small tip visible through said face, and a tube connectingthe bottomof the chamber with the main pipe and terminating within saidmain pipe in a tip curved in the direction of the flow of the beer.

In testimony whereof I have hereunto signed my name.
